Designed specifically for large-bore 3-inch swing-style check valves (commonly integrated with FIG 1502 hammer union connections), this comprehensive kit is a critical maintenance asset for ensuring safe, unidirectional fluid flow and preventing dangerous high-pressure backflow during heavy-duty well servicing operations.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eSwing type check valves feature a large clapper or disc that swings completely out of the flow path when active, making them exceptionally well-suited for high-volume, highly abrasive fluids containing frac sand, proppants, and heavy cement slurries. Due to the extreme abrasion, shock loads, and massive fluid velocities in 3-inch oilfield flowlines, the internal sealing mechanisms will eventually wear down. This repair kit allows field technicians to quickly swap out the worn internal components directly on location, dramatically reducing non-productive time (NPT) and eliminating the massive expense of replacing the entire heavy-duty valve body.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eThe kit typically includes a high-strength swing disc (clapper), a precision-machined seat, a heavy-duty hinge pin, and all required elastomer seals (O-rings\/packings) to re-establish a bubble-tight, leak-free seal under maximum working pressures up to 15,000 PSI.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eFeatures \u0026amp;
